Desulphurization of High Sulfur Coal by Mild Pyrolysis Combination with Magnetic Separation

Abstract:

In this work, a new desulfurization process of high sulfur coal was designed and examined. The novel process involved pyrolysis of high sulfur coal at low temperature and then a dry magnetic separation. For testing the cleaning coal process, a Chinese high sulfur coal, Baisu coal was pyrolyzed in a fixed bed reactor from 400 to 700°C for 30min, and then separated by a dry magnetic separator. The results showed that under optimum conditions, a remarkable reduction of sulfur content in coal was achieved, and more importantly, almost all pyrite sulfur in coal was removed.
